Application filed June 25,

This invention relates to car'roofs, particularlyinsulated car roofs of the type shownin my Patent No. 1,643,975, dated August- 4, 1927, wherein self-supporting roof sheets extend from side'to side of the cark and are rigidly connected along their adjacent mar-` gins by upstanding seams that function as outside carlines vand have lmembers secured therein'for stiflening said seams and for suspendingI the insulating lining beneath said roof sheets.

Iheprincipal object of the present invention is to provide a simple and eficientparrangement for attaching aload-l'ifting beam to roofs of the above type. Other objectsarel ease' of assembly, compactnessof design, fewi ness of parts and cheapness of manufacture;

"The inventionr consists principallyin the parts and in the construction, combinations and arrangements of parts hereinafter described and claimed.

my inventionis shown in connectionv with an all-steel riveted-up car roofl comprising metal roof sheets l, whichl extend from side plate 2 vto side plate 2alongsid`e of'each other' and "slope downwardly' on opposite sides of the Y ridge to formapitch or arcuate roof.A As shownfln the drawings, the side plates 2 yare preferably of Z-shaped cross-section and arek positioned with their .webs .horizontal Aand with their inner flanges 3 extending upwardj ly. 'The roof sheets-l are supported on and angle strips 4, which extend longitudinally of the carv with their other flanges proj ecting' downwardly and riveted flatw'ise to the outer faces of the upstanding inner flanges 3 of the side plates 2. f The roof sheets l are provided attheir eaves ends with depending drip flanges 5 that overhangthe outer edges of the eaves angles 4:.

Y .65 riveted to the outstanding top lflanges of eaves i flanges 6 and the body portions of said sheets'V Y are preferablyvoifset 'upwardly' adjacent vto Vsaidila'nges to form raised panels 7. `The side marginal seamflanges `ofthe-roof sheets are coped oif at the'eavesj'e'nds of the sheets andVV merge into theVv plane of the sideA Inarj ginal panelsf thereof. A -v Y Metal strips or plates f8.1of substantially angular cross-.section haveioneflange interposed between the adjacent side seam flanges c 6 of Vadjacent roof sheets, the 'otheriiange extending` beneath the vraised sideV marginal panel 7 of one roof sheet and: being'spacedl jvertically therefrom. Metal seamcaps 9 of substantially inverted U-shapedcrossfsection nef are placed astride adjacent side marginal seamflanges :6 andthe ,vertical flange of the strip 8 interposed therebetweenand are rivetl ed or otherwise'rig-idly securedfto saifd flanges to form an yupstandingl seamgconst'ruction that functions after-'the manner of 'an eX-V terior'carline for the roof. Y -Each seam is-proz vided withtwo ofthe angleshaped plates or Y strips 8 that extend from the side platesfto of the car at the ridge and are supported on f and rigidly secured to the lateral top flanges of angle-shaped running board saddles 12 that are secured to the sides of the seam caps. by the securing rivets therefor.

Bolted or otherwise rigidly secured to the underside of the lateral base flanges of the angle-shaped plates 8 embodied in each seam are vwooden strips 13 that ext-end longitudinally of said plates from the side plates to points short of the ridge ends of said plates. Each wooden strip 13 is rabbetedas at 14, along one of its upper corners to accommodate the baseflange of the seam plate 8 to which it is secured; andthe portion of said strip located on the side opposite fromsaid base .flange is preferably in contact with the raised side marginal roof sheet panel 7 located thereabove. Located below the wooden supporting strips 13 is aninsulating lining 15 of wood or other insulating material, which is nailed or otherwise rigidly secured to the undersides ofY said strips. The wooden strips 13 serve as nailing strips for the insulatinglining 15, and they also serve to space the saidy lining below the roof sheets V,and thus provide dead airV insulating spaces between the roof sheets and lsaid linings..

ends o-f the two angle-shaped plates 8 and stiifener 1n each seam for carline construction are connected together by means ofiasplice member lthat serves as a hanger for aload-v lifting beam 17 which extends longitudinally of thereof at the ridge, preferablyfrom-end to end of the car. Each of these combined splice members and beam hangers 16 comprises a channel-shaped body portion with outstanding top flanges 18 that are bolted or otherwise rigidly secured tothe bottoms of the ridge end portions of the base flanges of the two combinedhanger and Stiening plates 8 foreach seam. T he channel-shaped beam hanger 16 is locatedbetween the spaced ridge a ends. of the wooden nailing strips 13 that are bolted to the hanger plates 8 embodied in the seam; andthe load-liftingbeam 117 is shown inthe form of a metal member of inverted Vchannel-shapedY cross-section with outstanding base flanges19. The web or top portion of the invertedchannelshaped load-lifting beam 17 is riveted or otherwise secured flatwise tothe bottom of the web-of the channelshaped beam hanger 16, with the upper por- 20'which is'slidably supportedon `said flangesv and serves to support a suitable lifting tackle (not shown).

In the construction shown in Figs. 7 and 8, the roof is shown provided with asectional or built-up load-lifting beam 21 of channelshaped section with lateral top flanges 22 that are. bolted or otherwise rigidly secured directly to the bottoms of the ridge end portions of the base flanges of the plates 8 for each seam ,5 and thebottom or web of the channel is provided with a longitudinal slot 23 adapted to slidably receive a ring 24 for'supportingl a lifting tackle (not shown). `The ring-24 is 'slidably supported in the slot 23 by means of-laterally extending portions 25 at the top of said ring. The load-lifting beam 21 preferably comprises two side members or sections 26 kof Substantially Zv-shaped crosssection that are so arranged that their 'webs form the sides of the channel, theirY upper Y flanges formthe top flanges 22of said channel and their bottom'flanges form the slotted bottom of said channel.

It serves to connect together the ridge ends of the two plates embodied in each seam, thereby increasing the strength Yand rigidity of the seam; it permits the insulating lining to be removedv andreplaced without disturbing the lifting beam;
